General description

Protopine is a celandine alkaloid and a bioactive compound associated with the plant families including fumariaceae, berberidaceae and papaveraceae. It is metabolized by demethylenation in the presence of the cytochrome enzymes cytochrome P450 family 2 subfamily d polypeptide 1 (CYP2D1) and cytochrome P450 family 2 subfamily c polypeptide 11 (CYP2C11).

Application

Protopine hydrochloride may be used in the calibration curve preparation for the quantification of alkaloids from Fumaria capreolata using liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry (LC-DAD-MS) and tandem mass spectrometry(MS/MS). It may also be used as an alkaloid in cytotoxicity and permeability studies carcinogenic cell lines.

Biochem/physiol Actions

Protopine possesses anti-parasitic, antimicrobial and anti-inflammatory property. It mediates mitotic arrest by favoring tubulin polymerization. Protopine elicits anti-invasive effects in breast cancer tumor progression.. It also provides protection against oxidative stress-induced cell death.
Protopine hydrochloride is a Ca2+ channel blocker and antiplatelet agent.

Caution

Protect from light.

For the synthesis of protopine alkaloids, we studied a reaction sequence based on a ring enlargement of indeno[2,1-a][3]benzazepines by a singlet oxygen oxygenation, followed by conversion of an amide carbonyl group of the resultant 10-membered keto-lactam to a methylene group

A sensitive and specific liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) method has been developed and validated for the simultaneous quantification of tetrahydropalmatine, protopine and palmatine in rat plasma using phenacetin as the internal standard (IS). Two hundred microliters plasma samples were

Calcium and lipid peroxidation play important roles in oxidative stress-induced cellular injury and apoptosis, which ultimately cause cell death. In this study we examined whether protopine had a neuroprotection against H(2)O(2)-induced injury in PC12 cells. Pretreatment of PC12 cells with

In this study, we investigated the anticancer effect of protopine on human hormone-refractory prostate cancer (HRPC) cells. Protopine exhibited an anti-proliferative effect by induction of tubulin polymerization and mitotic arrest, which ultimately led to apoptotic cell death. The data suggest
